The phrase refers to the procedure necessary to rectify a condition where an excessive amount of fuel has entered an engine’s cylinders, hindering the combustion process. This situation commonly occurs when the engine is started repeatedly without fully igniting the fuel-air mixture, particularly in older carbureted engines or due to issues with modern fuel injection systems. For instance, repeated attempts to start a car with a weak battery in cold weather may result in this condition.
Addressing this condition is crucial for restoring an engine’s functionality and preventing potential damage. Allowing raw fuel to linger in the cylinders can dilute engine oil, reducing its lubricating properties and accelerating wear. Moreover, persistent attempts to crank an engine in this state can strain the starter motor. Understanding the techniques involved is beneficial for vehicle owners and mechanics alike, leading to quicker repairs and minimized downtime.
